T cult whom it may concern:

Be 1t known that I, ADOLPH ROSENBERG,

citizen of the United States, residing at Buf-y falo, in the county of Erie and State of New York, have invented certain new and useful be readily ap lied to an ordinary window sash, and wine i will form a convenient hanproceeds, the invention consists in certain constructions and arrangements of the parts that I vshall hereinafter fully describe and claim.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawing, in which: l Figure 1 is a perspective View of a window sash provided with a ventilator embodying the invention; Fig. 2 is a vertical sectional view through the lower rail of the sash; if ig. 3 is a longitudinal vertical sectional view on the line 3 3 of Fig. 2; Fig. 4 is a transverse sectional view through the lower rail of a sash provided with a modified forni of the invention; and Fig. 5 is a perspective view of the plate which is secured to the inner face of the rail in the modified form of the invention and carries the swinging closure, p0rtions being broken away.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by thesame reference characters.

4, and which serves to exclude any large particles of dirt from the building. Applied to the inner face of the rail l, is a plate 5 which is formed with an elongated opening 6 fitting over the inortisdportion 2 ol' the rail and sAsH-LIFTER AND vnnrrmrroa specification of Letters Patent.

Patented Aug. 1o, 1909.

l designed ttireceive tie fingers when raising or lowering the sasi. Extending around this opening 6, is an inwardly projecting flange 7 which provi( es a large bearing sur- 60 face for the iingers ifi/'hen manipulating the sash, and 5 *erves to eliminate any sharp gf edges which might-serve to cut or injure the ,ii fingers.

Hinged to the upper portion of the flange 7 at the inner `'edge thereof, is a swinging closure 8 which may be either swung downi. wardly so as to close the opening 6 in the j plate 5, or swung upwardly so as to ieave the said opening unobstructed. For the purpose of normally holding the swinging closure 8 in a closed position, a spring 9 is utili. ized, the said spring being shown in the presil ent instance as located at the hinged edge of the closure.

Projecting within the mortised ortion 2 of the rail from the plate 5 and a oye the opening 6, is a s ring arm 10, the end of which is extender downwardly and curved on the areof a circle,'as indicated at 10", so 30 as to engage the edge of the closure 8 and i hold the same in an open position against the action of the spring 9. The free end of the arc-shaped spring strip 10"V is normally forced upwardly' by a U-shaped spring l1 g5 secured to the plate 5 underthe opening 6. However, when this U-shaped springis compressed, the arc-shaped spring-10*l is sprung away from the edge of the closure 8 so as-to release the closure and permit the same to be moved into a closed position throu h the medium of the spring 9. Passing oosely through the flange 7 at the bottom of the opening 6, is a plunger l2, the lower end of which bears against the U-sliaped spring 11 so as to compress the saine when ushed downwardly, while the upper end is o'rmed with a head 12B. i Iny the operation of the device, the swing ing closure 8 is forced inwardly by manual means when it is desired to obtain Ventiletion from the outside of the building, the arc-shap'edvspring strip 10 serving to frictionally engage'the edge of the closure to hold it in an open osition, On the other hand, when it is desire( to shut oli' ventilation from the outside of the buildin it is merelyv necessary to press downwarr ly upon the head 12a and cause the plunger 12 to compress the U-shaped spring 11, the arc-shaped spring 10Ll being thereby sprung out of engagement with the closure 8 so as to permit of the same winging downwardly in a closed position. l

i' Attention may be directed to the fact that Sash is located below frictio'nally wardly projecting and inwardly offset tongues the openingin the outer face of the rail of the 1 the opening in the inner l face, so that when the closure 8 is svmug n1- wardly, the air follows a diagonally upward i path through the rail from the exterior of the building.

A modification of the invention is shown in Fig. 4, in which a foraminous plate 3a 1s`l employed on the outside of the rail, instead of the Wire netting 3, and in which the plate 5- which is secured to the inner face of the rail, is not formed with a flange 7. The swinging closure 8a in this modified form of the invention, is hinged at its lower edge to the plate 5a at the bottom of the opening therein, and is` mounted to swing outwardly. Riveted or otherwise securely fastened to the swinging closure 8, is a handle 13 which is designed -to be grasped when' moving the sash either up or down within the window frame. Theftwo ends of the swinging closure 8a are provided with the inwardly extending segmental flanges 14, the upper edges of which engage the top of the opening in the plate 5a and serveto hold the swinging l closure in yan adjusted position. In the specific manner of connecting this -swinging I; e osure to the plate, shown on the drawing, 1 it will be observed that the lower edge of the swinging closure is formed with the down 16 at the bottom of the When no ventilation closure is swung upopening in the plate i air is desired, the i 15 engaging notches opening in the plate. is desired, the swinging 4wardly so as to close the 5, While when fresh n closure is swung outwardly to leave the opening in the'plate 5a partially unobstructed. Attention maybe directed to the fact that in this rnodiiedform of the invention, the o enings in the front and bac-k ofthe rail l oiP the sash, are located directly o `)posite to-'each other, the air being detlecte upwardly as it enters the room by means of the swinging l closure, and a direct draft being thereby A prevented.

l projecting inwardly from Having thus described the invention, what Ielaimis:

1. The combination ol' a sash formed with a rail having an opening extending therethrough, a plate applied to the rail and formed with an opening corres onding to y the openingtherein and designe( to receive the fingers when moving the sash, a flange l the plate and suras to provide a the fingers when rounding the opening so large bearing surface lor manipulating the sash, a swinging closure hinged to the fiange, a spring normally holding the swinging closure against the iiange so as to close the opening, and means for h olding the swinging closure in an open position.

2. The combination olI a sash l'ormed with a rail having ai opening extending through the same, a plate secured to the rail and formed with an opening corresponding to the opening therein, a swinging closure mounted upon the plate and normally closing the opening therein, and an arc-shaped strip adapted to engage the swinging\edgc of t 1e closure to hold position. t,
